So the current = 5.64/5 = 1.128 Amps
So the current = 5.64/5 = 1.128 Amps

====Resistance====

+Resistance is an electrical concept that simply relates current and voltage. It can have very low values 0,.001 ohms(Ω) is the resistance involved in semiconductors and we can also deal with Megaohms, the resistors used in Power Distibution. This is a incredible range of values, but for most electronic use the values are from a few Ω to 10 or so Megaohms, since these are the values resistors can be bought in.
+
+Your meter will measure a resistor in a similar fashion to how you use a multimeter to Voltage. You set the meter to Ohms(Ω) and place the two wires on the ends of the resistor. and the meter display will show the resistance. But there is something subtly different here. To perform this measurement there must be a voltage across the multimeter wires and the meter is actually measuring the current flowing and calculating the resistance to display.
+So there is actually a voltage across the multimeter when set to Ω. Indeed I use it to test LED's a working as it's only 1 or 2 volts. But it isn't a proper power supply. If you measure a Pi this way you may get a reading, but don't expect that to tell you how much current the Pi will use. There are semiconductors(lots of them) in the Pi and these do not present accurate resistance readings in such cases . .

+And then we come to
+====Continuity====
+Resistance's rougher cousin.
+
+Frequently, for instance when soldering, you aren't worried as to what the resistance is you simply want to know that electricity has gone where you hoped it would go. And you don't want to be distracted by having to look at the meter screen, you want a noise that indicates when the two leads are directly shorted to each other.
+
+Continuity.
+
+It beeps when the leads are shorted. The meter displays something but I don't think anybody ever reads it.
+This is the mode to use to check soldering.
+
+It checks that things that should be connected are.
+It checks that things that shouldn't be connected aren't.
